Abstract

PURPOSE:To attain a high-speed reading of the original with a high image resolution, by reading the fixed range where the originals overlap partially with every carrying step of the original via the 2-dimensional image sensor. CONSTITUTION:2-Dimensional image sensor 6 is provided, and original 1 shifts intermittently on the original board by conveyer belt 2. And sensor 6 performs the optical storage with every stoppage of original 1 for the screen of the original positioned within an image pickup range P and according to the quantity of reflected light of each part, and then generates the charge according to the light quantity. This charge is transferred to the shift register by the transfer pulse supplied from the controller and then read successively by the reading pulse to be delivered in the form of picture signal (a). Then signal (a) is delivered through signal processing circuit 7 in the form of binary coded effective picture signal (b). In such way, sensor 6 can read the entire screen of original 1 through N-times reading.
